SHEET-HANDLING llIACHINE.

Application filed June '18,

Z '0 all whom it may concern:

Be it known that I, .AnNoLD A. Sorrwan'rz, a citizen of the United States, residing at Dunellen, in the county of liliddlcsex and State of New Jersey, have invented certain new and useful lm )rovcments in Sheet- Handling h lachines, of which the following is a specification.

The invention relates to machines for operating upon sheets and more especially to mechanism in or auxiliary to a printing machine for operating upon previously printed and usually folded sheets, including mechanism receiving, folded sheets from a folding mechanism and then slitting and delivering them. 4'

()bjects and advantages of the invention will be set forth in part hereinafter, and in part will, be obvious herefrom, or may be ascertained through practice with the invention.

The invention consists in the novel parts,

constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constit-nting'a part hereof, illustrate one embodiment of the invention, and together with the description, serve to ca;- plain the principles of the invention.

Fig. 8 is .a fragmentary side "elevation of they delivery cylinder. shown in. end elevation in Fig. 3 and the following figures, but with much of the exterior of the delivery cylinder omitted to show the interior mechanism; and

Fig. 9 is a continuation of Fig. 8, joining at or near the right hand end thereof.

In the exemplary embodiment of the invention disclosed herein, the main features thereof comprise novel devices or mechanisms designed to cooperate with a fast running printing andfolding machine for transferring the folded sheets from the folding mechanism to the delivery mechanism, and in conjunction therewith de vices for slitting a long folded sheet into a plurality of signatures.

The mechanism transfers the folc ed sheets by their folded edge from the folding jaw to, and registers it preparatory to slitting by means of, one or more registering: jaws, the registering action being effected by a difference in speed between the folding jaw and the registering jaw, the latter in the embodied instance travelling more slowly. These mechanisms also act to gradually slow down a folded sheet or group of signatures from a relatively rapid sheet cutting or sheet collecting and f line: movement to a relatively very slow delivery.

More particularly, in this exemplary embodiment, the relatively long folded sheet is delivered from a relatively fast rotating folding jaw to a more slowly rotating registering and transferring jaw on a slower moving delivery cylinder. the folding jaw delivering or transferring the sheet directly to the registering aw.

The long folded sheet is thereby positioned and registered on the delivery cylinder preparatoryto slitting, it being preferable as at pr sent adv1sed to effectthe slitting; on the delivery cylinder. After the folded sheet is so held and registered, it is, slit into i a plurality of signatures, and preparatory to the slitting, a plurality of holding ,{IIIP- pers grip each part or section of the folded sheet which will constitute a, separate signature when the relatively long folded sheet is slit in a direction transversely to its fold.

At the delivery position, the registering jaw or jaws and the holding grippers re-- lease the varmus signatures or slit sections ot the original. long folded, sheet or sheets, so that they may he delivered to a suitable storing' or conveying away device. In the exemplified In achinc, four sheets are usually- :tolded at once and so are slit together mat:-

3 ing of each slit part a signature oil sixteen pages open at all. three edges thereof.

In conjunction With the features and oa aspects the invention is not essentially limited to thergeneral statement already made of the main features of the exemplifiedembodiment.

Referring now in detail to the embodi- Inent of the invention illustrated by Way of example in the accompanying drawings, there. is shown in Fig. 1: the main features oi a sheet cutting, sheet collecting, ikilding and signature slitting mechanism, which is adapted to. receive a web oi? paper printed on both sidesirom a rotary printing press. perform thereon the operations indicated and to deliver the (cut apart sigi'iatures.

Machines oi" this type are designed to operate at relatively high speed and at the same time to turn out a very high-class product, such as Will be acceptable for magazine andperiodical Work. That is, they are machines approximating as nearly as possible to newspaper speed While maintaining as nearly as possible hook-print quality. In this class of Work, the printer-l u eh must be received very rapidly from the press and .must be handled very carefully and nicely and preteral'ily with lessening speed during the subsequent operations. such. as cutting. collecting, and especi'z-illy during told' 1g, slitting and delix 'ering. The present invention is directed largely to u'ieans and devices tor improving such subsequent handling of the printed sheets. i

In this embodied er eniplification of the ionl the u'ehe: 1? rece ved from the is or other source oil su i iily and pawns over a guiding roller 1 to rotary slittcrs iand 3 which may he of any suitable or ronvenient form, and which transversely sever. or almost sever, the printed-Web, When the web not entirely severed, the severance completed: when the head the sheet is taken by the collecting grippers. As shown may compr se a cylinder or series of discs scribed or shown in detail.

or like device mounted on a shaft 13, and provided with two dia'metrally disposed knii es 5 and (tyiii'ul an opposed and cooperating cylinder, or other like device, mount-- ed on a shaft 14-, and having two grooved blocks 7 and 8, coopeiating respectively, With the knives 5 and 6 to separate or to serrate the Web, n: to separate the sheets or to prepare them for separation.

The lead of the Web passes thence downwardly between two opposed, rertiiizally disposed series ot guiding fingers 9 and 10, supported on transversely disposed rods 11 and 12, supported in the machine frame.

v The sheets out from the web are preterahly collected prior to being folded, and? as embodied a collecting cylinder i5 is pro Vided, mounted on a shaft 1-, journaled in the machine frame. Cylinder 155' has three sets of grippers 16, 1'7 and 18, each set constructed and operated to receive one sheet on top of another successively and then to discharge the hundleor group of sheets. As the form cylinder of the press had four plates or page forms around the A suitable tucking roller also shown, tor tucking the lead or head of the sheet or eb a? into the approaching gripper each oil the gripper spaces upon the c n der. The group of t'ourshoets is taken only way of example. as the filly applicable to any ll "1 rd number To of t tl-'= Fol o 'i'e p tion a h r pers on the collecting tl' is. transrcr \ly of and at tl ie-n=....tlle of each group ()l' sheets.

The folding jaw as to its general striutture andmanner ol" operation is of the floating; typo, wherein the entire il olding jaw structure has a n'iorement to cooperate lirstwith the 'lr'lldingi blade or blades to fold and to talre the group of sheets away by their "folded edge, and then to deliver the folded sheets. and having; also an intervening' inoven'ient in the l'lilllfilllllg of the sheets while carried by the jaw. In addition. one of the jaw ZGGTnlIlQIFS has nove- Inent relative to the other to close on or bite the group of sheets over the fohlingz; blad between, jaw 2 and cooperatii'ig jaw or jaws 4-5. to make the fold therein and to carry the so folded sheet or sheets away from the folding blade and its carrier. and to carry it to the place 0% delivery. Such a mecha nism is shown in U. S. Potent lrlo. 629.9528 to Seymour, dated August 1.. 1899. and. the mechanism need not be described further in detail. It will be su'llicient to state that the combined or entire folding jrw structure is carried on two supper l 0 arrns 26, fixed on a shaft 2? w ich is jour aled in the machine frame and suitably driven. To give the oesired floating action. the

folding 24L is carried on arms 31; journaled by shatts 32 in the arms 26 and heing rotatable with respect to the rotating; arms 26. Connected to arms 31., through these hearing shafts respectn. y, are one or two actuating arms 34. havi g cazn rollers 35, runningin earns 86., carrieiil on the ma.- chine frame. It will he su'liicient here to state that this controlling inechanisn'i brings the folding jew mechanism to the position shown in Fig. 2 to receive and told the sheet or group ofsheets. and to then carry them away by the tolded edge to be livered to and operated upon by the subsequent mechanisms. i

The delivery action and position are shown in l iqs. 3. and tollowingg as el'lected in the present embodied machine. As slatei h this me Illtlllllll'll is old and well .lrnown as is also the mechanism for opening and closing; jaw 4:5 against. jaw 24 to make the fold and to deliver the sheet and need not he described in detail.

xi is crmstructed, the jaw la": is pivoted on a shaft 4:6, and ll'lOVUS to and from the w E l l: to pinch or bite the sheet. over the folding blades 19, 20 or 21, thereafter holding the folded edge of the sheet, and opening, as shown in Fig. 4%, to. release the group of sheets when it is taken. by the j av 42 on the del i very cylinder. The nisin for opening and closing the aw in timed relation may be of any convenient or standard construction, such mechanism in. detail, as before stated, being old and wellknown, and is omitted herefrom for the sake of clearness.

Referring now to the embodied actuating means for the holding and registering jaw or jaws 42, whereby they are operated to take the group of'sheets from the folding jaw and to hold it for the required time and to release it for delivery, the body d3 of the aw is pivoted at its inner end L9 to an arm 5 l.he arm is fixed to a shaft 51, which shaft j ournaled in the cylinder 40, and disposed loz'igitudinally of the cylinder. lifleans are provided, as en'ibodied,

for yieldingly holding the jaw ll in the closed or sheet-engaging position, and cooperating therewith are cam-opeated means for opening the jaw against the action of In. said means, there is fixed to the shaft 51, an arm 52, pivotally connected at the outer end thereof to a rod 53, which rod is longitudinally slidable within a lug 5 L mounted on one of the internal cross-webs of the cylinder 4-0. Coiled about rod 54 is a spring); 56, in COIIIQI'DSSiOI] between the head of rod 53 and lug 54., therein; deldingly or resilientl y pressing the l'iolding jaw 41 in closed position.

The embodied canroperated means for opening the j aw against the pressure for spring 56 comprise; an arm 58, lined to the end of shaft .31..

whe e it projects beyond 1 outside the o inder P and thiirhroller mi co-ope .4 with a cam 1:50 which is mounted on the sine frame iii of the mar-hi; the ram being ta pared at its enterini end, left hand endin ,l ig. 3, to receive the roller 59; ln Fig. 3-, the lowermost hiildin jaw ll is shown approaching the dolive 1 position, with its cam roller 59 riding onto the tapered point of cam 60, and upon the roller striking the operating surface of the cam, this jawill will open to deliver the sheet. The topactiuiting mocha.

most holding jaw ll. in Fig. has its cam roller 59 riding: on or near the end of cam (30, whereby the holding jaw is. held open. As it is about to. receive the folded edge of the sheet from the folded jaw 2 1-, thi caniroller 59 is about to ride off the end of the cam 60, when the upper holding jaw 41 will snap down. on the folded edge of the group of sheets just immediately before, or at the instant of, the release thereof by the folding jaw 24:.

lin accordance with one feature of the inigention, and as already generally stated, the long folded. sheet. or group of folded together sheets is transversely slid into a plu rality of signatures. This is effected in the present embodiment (see Figs. 1, 3, 6 and. 'i'), by means of rotary slitters 61, which are mounted on-shaft 63, and arc/shown as three in number. These slitters 61 are arranged along the cylinder i0, whereby the longfolded group of sheets or signature, is.transversely slit into foursignatures. lVith the collecting cylinder, as already described, collecting four sheets in superposition and folding them off simultaneously, and thereafter slitting the long folded group of sheets into four signatures, there is produced. at each. folding operation four signatures of sixteen pages each, or sixty-four pages in all. The s'litters (31 cooperate with corresponding elements, such as grooves 62, formed in the cylinder 40 (see Fig. 8).

To provide for holding the folded sheet firmly during the slitting operation,-ai1d to provide also for holding the separated or slit apart signatures after the slitting and prior to delivery, a plurality of cooperating grippers are provided, which grasp the group of sheets at the folded edge, just after the release thereof by the folding jaw 24, and the taking thereof by the hold;- jaw 41, and prior-to the slitting operation. These grippers hold the sheets or signatures until they are released for delivery. There are two such gripper mechanisms-shown on cylinder 40, a semi-circumference apart, e eh cooperating -with the. corresponding holding jaw or jaws 41. One description will. suilice for both groups, they may be the same or similar inconstruction. V

In the embodied form of construction, thedesired number of grippers 65 are prw vided in, each such mechanism, preferably one gripper 65 at either side of each of the rotary slitters 61. The grippers 65 are mounted within the cylinder t0 and. are preferably of the type which swing back below the ieriphery of the cylinder 40 when opened. As embodied, the grippers 65 are fixed on a shaft66 (Figs. 3, 41-, 5, 6, 7 and 8) which is journaled in cylindereO and is disposed longitudinally thereof. 7

The actuating means for grippers 6500mprise a, double cam-arm, or tripper block 67, fixed upon the end of shaft 6'6 where the shaft projects from the end of cylinder 40 The arm or tumbler S7 is provided with two cam-slots 6S and (it), located at either side 01? the shaft ll'iounted on the machine frame are tripping pins 70, adapted to enter the cam-slots (58 and (59 to partially rotate shaft 66 and thereby to tumble grippers (55, to close the grippers at the sheet receiving position and to open them at the sheet delivery position. As embodied, a tripper pin "Z is located at the sheet-reci-iiving position, the pin being positionable, or adjustably positionable, .to vary the tiinii'ig of the grippers. For this purpos pin 70 is mounted in a boss 71 on a plate or arm 72, which plate is journaled or hung on the shaft ll (Figs. 1 and 8) of the delivery cylinder. ill-in 72 at its outer end has formed therein a, slot through which projects a screw-bolt 7-1, which. is screwthreaded into the side frame 43 of the maci e, i iocsening the screw-bolt 74, arm 72 may swung more or less, thereby vary- J the angular location of the pin 70 to change the timing of the gri 'ipers. When in "F0 in desired position, the bolt 7-1- ,F be screwed down tightly to hold it in this nun-hanism is shown in dupli- 2i and i both the sheet 1 sheet delu y positions of the grippers (l5. @ach oi the turncooperates with each oi? the I p ill, with one pin to close the llljluifs on the sheets, and with the other pin to release the sheets at delivery positio is.

[is embodied, an arm 'ed to shaft (35, and pivotally contht-wcto is a rod 78, the other end of it p .ng through and being longiidable in a lug 79 mounted on two sets bier tr rod tudinally one oi the cross-webs 80 of the cylinder 40 (Figs. 3 and S). Coiled around rod '78 and in compression between the head of rod 78 and the h1g7?) is a spring 81. The construction is such that when the gripper is open, arin ii is thrown to one side of the center line betwiaai lug T9 and shaft (36, and when the gripper is closed arm ll is thrown to the oppos te side of in center line lietwwii lug aha it till, thereby ln'ilding the gripper opener closed under spring pressure, permitting it to be moved from one posil to the other by the actuating mechanism in accorihince with one feature of the invention. the cylinder or like element all.) is run at a slower peripheral speed than that of the folding jaw 24, thereby providing a slowing down step in the delivery of the product, and also affording a reliable registering action t'or the holding jaw or jaws 4-1 in taking the folded edge of the sheets. In the present preferred form, the folding aws travel or rotate at approximately half the peripheral speed of the collecting cylinder 25, tne motion of the folding jaw on its carrier con'ipensa ing for this, and in turn the delivery cylinder it travels or rotates at approximately half the peripheral speed of the folding aw, for the purpos s already stated.

Suitable means are providedfor receiving the folded and slit signatiiires from the cylinder. ll), and these may be of any desired or convenient form. As shown herein (Fig. 1) a usual form of belt or apron delivery is provided, comprisinn' a belt 88, running over rollers 84:, and driven in any suitable manner. Stripping fingers 85 cooperate to insure the delivery oi the signa tnres from the cylinder to the belt.

The manner of operation of the mechanism described will be understood from the foregoing, but it may be stated by way of resume as follows: In Fig, 3 the mechanism is shown just prior to the release by the folding aws 2%, hi of the folded edge of the long signature (which is tour pages long), from the tolding jaws, and just as the folded edge is registering against the jaw .13 beneath the head 12. At the lower end oil? Fig. 3, the grippers (35 and holdingjaw 41 are approaching the delivery position where they will both release the sheet.

in Fig, 5 the mechanism is shown snbstaan tially in the same position as in l ig. 23, but with many oi. the parts omitted in order to show with greater cleai'ness the construction and operation of the remaining parts.

In Fig. a the folded sheets, that is the long signature, is shown held and registered b; the holding jaw 4-1, the opened folding jaws 21-, departing along its path oi travel, atter having released the folded edge of the signature, and the grippers are shown approaching in their revolution or closing action and about midway in their movement, to close down on the -folded edge of the sheet as shown in Fig. (3,

In Fig. (3 the uppermost mechanism shows the sheet in the grip ol" the holding jaw and with the grippers (35 also closed down on the ti'ililed edge oi the sheet, which is apn'oaching the rotating slitters (31, preparatory to the long t-llglltltlll'fi being slit up into iour signatures, each of page length. At the bottom of Fig. (3, the holding aw ll and the grippers as are shown in open position just having released the slit siginitures for delivery. i

T he invention in its broader aspects is not limited to the particular construct-inus here-- for causing said jaw and holding means on the delivery cylinder to release the slit sheet or signatures for delivery.
